AUTOMATIC EGG GRADER.

Application filed January 5, 1922. Serial No. 527,163.

To all whom it may concern:

Be it known that I, EDWARD GOODWIN, a citizen of the United States, anda resident of Folsom, county of Sacramento, and State of California,have invented a new and useful Automatic Egg Grader, of which thefollowing is a specification.

The present invention relates to improvements in grading devices and hasparticular reference to a device for grading eggs, Its principal objectis to provide a simple means whereby eggs can be quickly gradedaccording to their weight. Another object is to provide a grader that issimple and economic in construction, does not require any adjustmentsfor the weighing of each individual but automatically indicates thegrade of the egg immediately after the same has been placed on thegrader.

The preferred form oi my device is illustrated in the accompanyingdrawing in which Figure l represents a side elevation oi? my device andFigure a top plan view of the same.

The balancing lever (i) is made of a single piece of wire, forming loopsand (3) at its ends and a diamond intermediate of its length, the latterhaving loops (6) and (T) rising from its extreme, corners. This lever ispivotally supported on the standard (8)-also preferably made of a singlepiece of wire and forming two upright members (9) secured to the. base(11) by means of the screw (12) engaging the horizontal member (14:)connecting the upright members, hooks (16) bent into the wire adapted toengage the loops (6) and (7) and the two horizontal upper members (I?)engaging each other at (18) where they are twisted together. Thistwisted portion is bent downward at (20) and ends into the fork (19)adapted to engage the arm (21) of the.- lever (1) whereby the latter isprevented trom rising above a. level position under the influence of theother arm (2-2) and the weight secured thereto. From the end of the armis suspended the ring (24) connected thereto by the wire (26). h ring isof such dimension that it will easily hold an egg placed thereon.

The arm carries the weight (31) which is pivot-ally suspended therefrom.The wei ht is provided with loops and (33), the former extendingupwardly and engaging the loop (3) at the end of the lever arm (22),while the latter extends downwardly and engages a similar loop (3 1-)rising from a second weight This weig t normally rests on a third weight(87) supported on a block (38), which latter weight is provided with anupwardly extending rod (39) passing through a perforation (41) in theweight and provided with a head (42) looking it to the latter weight,but allowing the latter a limited freedom of vertical motion beforeengaging the third weight.

In operation the eggs to be graded are successively placed on the ring(24). It is assumed that it is desired to establish three gradescorresponding to the weight of (31) alone, or" (31) and (36) combinedand of (31), (36) and (37) combined. \Vhen a light egg is placed on thering, itmay raise the weight (31), but will not raise the weight Amedium weight egg will raise both the weights (31) and (36), while onlya heavy egg will raise all three weights. Suiiicient play is allowedbetween the weights so that the weights distinctly indicate the grade ofthe egg.

To-enable the operator to balance the device before the weights areattached, I pro vide a threaded sleeve 4-3 on a threaded arm ll formingpart of the lever 1. The threaded arm extends preferably beyond thetulcrum of the lever, as shown in the drawing so that the sleeve 43 maybe adjusted to bear down on either one of the arms of the lever.

I claim:

1. In an egg grader of the character described, the combination of. abalancing lever having an egg receptacle suspended from one end so thatthe same is normally balanced by the other end and a selective weightsystem associated with said other end comprising a lower weight normallyresting on a. stationary support, a second weight normally resting onthe lower weight, arod extending from the lower weight through thesecond weight having a head thereon adapted to limit the travel of thesecond weight relative to the lower weight, a hook extending upwardlyfrom the second weight, and a third weight sus pended from the lever armhaving a downwardly extending hook engaging the former hook for limitingthe travel of the third weight relative to the second weight.

' 2. An egg grader comprising a base, two wire standards rising from thesame in spaced relation each terminating in a hook, a balancing leverconsisting of wire bent into diamond shape with loops provided at twoopposing corners adaptedto engage the hooks of the standards andrectilinear extensions emanating from the two other corners, an eggreceptacle suspended from one of the extensions and a weight suspendedfrom the other extension.

3. An egg grader comprising a base, two wire standards rising from thesame in spaced relation each forming a hook at its upper end and bothextending beyond the hooks and terminating in a downwardly pointingfork, a balancing lever consisting of wire bent into diamond shape withloops provided at two opposing corners adapted to engage the hooks ofthe standards and rectilinear extensions emanating from the two othercorners, one of the extensions being adapted to engage the fork forlimiting its upward motion and having an egg receptacle suspendedtherefrom and the other extension having a weight associated therewith.
